Product Technical Specifications
IMScrews 1/2-13 Flange Nuts are engineered from reliable 18-8 (304) stainless steel, offering consistent resistance against rust and environmental elements. These heavy-duty fasteners feature a serrated flange base that provides a strong grip to help maintain a stable connection in environments prone to high vibration. With a wide 25.5mm bearing surface, these nuts effectively distribute load across the material, preventing surface damage and ensuring structural integrity in professional assemblies

Design and Application Guidance
Designed for structural durability, these serrated lock nuts are a dependable choice for automotive chassis, suspension components, and outdoor construction projects. The integrated flange design eliminates the need for separate washers, streamlining the assembly process. Please note that while 304 stainless steel is highly reliable, these fasteners may exhibit a slight magnetic pull due to the intense cold-forming process used for heavy 1/2-inch hardware; this is a common physical characteristic and does not affect performance or corrosion resistance.
